Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"trinh ve va snippets" » "trinh he va snippets", "trinh va va snippets", "trinh vi va snippets", "trinh ve van snippets", "trinh te va snippets", "trinh ke va snippets", "trinh ve va slippers"
"locating bug code snippets" » "locating bug code slippers", "locating bung code snippets", "locating bugs code snippets", "locating bug core snippets"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"python using java snippets\") OR (\"trinh ve va snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( trinh ve va snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("trinh ve va snippets"))) OR ("locating bug code snippets"))*.
